Really hoped by now, that '13 and '14 (this year's warranty expiries) owners would pioneer the way, but battery solutions look undecided. Options for aged, partial refurbs, or the alternative $~20k (w/o history?) from Tesla is all we have? Service plans (aka W057) are clever, but not something I'd guess many would lean on; too small a business to assume the role of insurer.
Is there any hope for those of us with tools/lifts/etc., buying used packs, possibly from dismantled cars whose histories are known, then bolting them on in little more than 10X the time it would take Tesla to speed change a pack? My hope is shops develop more "a la carte" ways, with known solutions; solutions including 100KWh packs in older cars, like Mr. Hughes P85D.
Things still feel like they're just getting going. 22k 2013's, then 35k 2014s (global) come off 8-year warranties this year. We still have to see what Tesla does in CARB states, where the law says 10, not 8, years of coverage. If someone tests this, do they honor, etc., etc.?
